摘要 土地利用類型總體規(guī)劃是國(guó)土資源局為了實(shí)現(xiàn)合理管理土地，提高國(guó)民經(jīng)濟(jì)在各部門之間進(jìn)行分配的必要做法，因此，對(duì)土地利用的定期評(píng)估也是不可或缺的步驟。展開(kāi)對(duì)土地利用類型總體規(guī)劃的評(píng)估分析，既可以推動(dòng)時(shí)代經(jīng)濟(jì)的發(fā)展變化和需求，也可以在國(guó)民經(jīng)濟(jì)、生態(tài)環(huán)境、社會(huì)關(guān)系及土地可持續(xù)利用等多方面有很大促進(jìn)。當(dāng)前的評(píng)估多數(shù)是通過(guò)建立指標(biāo)體系進(jìn)行數(shù)量上的評(píng)估，這種評(píng)估不能反映土地利用在空間上的差異。以甘肅省張掖市民樂(lè)縣永固鎮(zhèn)為案例，利用ArcGIS的空間分析工具，構(gòu)建了空間吻合度、空間重心偏移度、環(huán)形分析系統(tǒng)3個(gè)模型，分別在執(zhí)行過(guò)程吻合性和結(jié)果吻合性、農(nóng)村居民點(diǎn)重心偏移程度及農(nóng)村居民點(diǎn)空間圈層布局等角度，對(duì)土地利用類型規(guī)劃實(shí)施7年（2009—2016年）來(lái)的效果進(jìn)行分析評(píng)估。研究表明，永固鎮(zhèn)土地利用類型總體規(guī)劃的實(shí)施在很大程度上是以規(guī)劃為主的，沿著規(guī)劃的方向發(fā)展，較好地完善了土地合理利用和空間管制;空間吻合度、空間重心偏移度及圈層系統(tǒng)分析模型在規(guī)劃實(shí)施評(píng)估中整體效果不錯(cuò)，適用性比較好。此次評(píng)估實(shí)現(xiàn)了方法上的創(chuàng)新，打破傳統(tǒng)定性定量的分析，有效完善了規(guī)劃實(shí)施評(píng)估的研究方法，拓展了評(píng)估分析空間。

Abstract The overall planning of land use types is a necessary practice for the Land and Resources Bureau to realize rational land management and improve the distribution of national economy among various departments. Therefore， the regular evaluation of land use is also an indispensable step. The evaluation and analysis of the overall planning of land use types can not only promote the development and changes of the times economy， but also greatly promote the national economy， ecological environment， social relations and sustainable land use. At present， most of the assessments are carried out quantitatively by establishing an index system， which cannot reflect the spatial differences of land use. Taking Yonggu Town， Minle County， Zhangye City， Gansu Province as an example， using ArcGIS spatial analysis tools， this paper constructs three models： spatial coincidence degree， spatial center of gravity offset degree and ring analysis system， and analyzes and evaluates the effect of land use type planning after seven years implementation （2009-2016） from the perspectives of implementation process coincidence and result coincidence， degree of center of gravity offset of rural residential areas and spatial circle layout of rural residential areas. The research shows that the implementation of the master plan of land use type in Yonggu Town is mainly based on planning， and it develops along the direction of planning， which improves the rational use of land and spatial control. Spatial coincidence degree， spatial center of gravity deviation degree and circle system analysis model have good overall effect and good applicability in planning implementation evaluation. This evaluation has achieved innovation in methods， broken the traditional qualitative and quantitative analysis， effectively improved the research methods of planning implementation evaluation， and expanded the evaluation and analysis space.
